ANALYSIS OF CLASSIFICATIONS OF THE TESTIS ALTERATIONS IN MALE-STERILITY

An analysis of the authors' own data based on the examination of 697 testis biopsies is given. The material is subdivided into two groups depending on the presence or absence of germ cells: 1) hypospermatogenesis and 2) aspermatogenesis. Hypospermatogenesis is related to any tubule changes resulting in the hypoproduction of spermatozoa. Criteria of tubule changes and a method for determination of the hypospermatogenesis degree are given. Insolvency of some existing histologic classifications is shown.
